BRAKE-SHOE FOR LOCYOMOTIVES.

' Beit known that 1HENRYH. URQUHART, a. citizen .of the Umted' States, residing at Paducah, in the county of McCracken and State of Kentucky, have invented a new and useful Brake-Shoe for Locomotives, of which the following is a s eciiication.

improve the construction vof brake shoes for The invention re ates .to improvements in brake shoes-for locomotives.

The object 'of the present invention .is 'to locomotives, 'and to providea. simple and comparatively inexpensive brake `shoe of in` creased efiiciency and greater strength and durability. Y y

Withthese and otherA objects in view, the invention consists -inthe -construction and novel combination ofparts hereinafter fully described, illustrated in the accompanying drawing, and'pointed-out in the claims heretoappended; ,1t being understood. that various changes inthe form, proportion, size an minor details of construction, within the scope of the claims, may be resorted `to with- Aout departin from the spirit-,or sacrificing an ofthe a vantages ofthe invention.

n the drawing z-Figure` 1 is a side elevation of a brake shoe, constructed in" accordance with this invention. Fig. 2 is a central vertical sectional view of the same.

spending parts in allthe figures of the draw l 1 A Iiglhe brake shoe-consists of a body'l of gray iron or oth'er suitable material'and areinforcingframe 2 of steel, embedded in the body 1 b molding the latter around the former.

brake shoe, which is provided with a wheel engaging face 3 of the usual configura tion, has a recess or depression 4 at the back for the rece tion of a brake head 5.

The re' orcing steel frame, Which'preier f abl consists of a drop steel forging, is located wit in the recess or depress1on and constitutes the major ortion ofthe rear face of the brake shoe, an it is provided witha cen-l trally arranged steel lug 6. The steel lug 6 isv provided with 4a transverse opening A7, lthrough which passes a transverse bolt 8 for securing the brake shoe to thehmke head.

y Specication of Letters Patent.- A Appiiaion findsepambef 9.1907. serial No. asista 'dove-tail joint or connection, an sid e arms .are located at the-center and a't points between the center and ends vof the Fig. .3 is

a transverse sectional view on the line 3-3' of Fig. 2. Fig. 4 is a detail perspective view 'of the brake shoe.

patented Jan. 28', 190s. l

I The brake shoe is curved-longitudinally' and the reinforcing frame is curvid to conform to the'curvature of the former, and the said frame is provided at opposite sides of the lug 6 with longitudinal openings' 9, whichreceiveportions 10 of metal of the body ofthe brake 4shoe, whereby the reinforcing frame is more securely united at the central portion with the. body of the brake shoe to effect amore ri idv body of the brake shoe.

arms 11 and 12, which extend through the l marginal side and end walls 13 and I4 of the The side Iand endl recess or depression 4. arms areoppositely beveled to Arovide a rame, as clearly illustrated in Fig. 5 of. the drawing. The' end arms arealso o .connection between the steel lug andit e The sides and endsl 1 of the frame are interlocked with the body of .the brake shoe4 by means of side and end the said y cated at the center and side portions of the ends ofv the frame, the end arms being spaced apart by 'longitudinal slots 15, which receive por-j' The outer face4 of the reinforcin 'steel l portions 1Q an 16 oi.

The brake vided-in itsfront connecting portion or wall head is hollow, and it is pro 8.5 17 with an opening 18, through whichv the lug 6 passes, and -the side walls of the brake.

head are pierced bythe transverse bolt 8. Y

rifhe transverse bolt 8 is providedA at one enda witha head,-and it is threaded at the other end to receive a nut 1'9, and it has a perforaltion for the reception of the key-...20. The

connecting wall or face 17 is also provided with a central longitudinal vgroove 21, which affords the necesary clearancein placingthe brake shoe on and in removin sion or'recess of the body are provided with notches 22 to enable the head of the .bolt and that t e brake shoes thereof areinterchan ef it from the" vbrake head. The side walls o the depresable. The steel frame imparts 'to the bra bhoe the strength ofl a solid steel shoe in the' connection of the shoe to the brake head,`

and the embedding of th-e reinforcing steel uit frame in the brake shoe by molding the bodyy i around the frame provides a perfectly safe shoe, which possesses the' durability and strength of a solid steel shoe;

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A brake shoe consisting of a body provided at the back with a depression or recess,

, having a surrounding marginal wall .at the ends and sides, and a reinforcing frame ern bedded in the body at theiback thereof and having arms or ortions extending through the marginal wa l to the exteriorthereof.

3. A brake shoe consisting of a body having a depression or recess, and a reinforcing frame embedded 1n the body at the recess and provided with side and end arms beveledat the edges and extending throu h the side and end Walls of the recess or e ression, said frame being also provided Wit 'central and end longituf inal slots or openings, which receive'portions of metal of the body.

4. A brake shoe consisting of a body having a depression or recess, and a reinforcing frame embedded in the body at the recess and provided with side and end arms eX- tending through the side and end Walls ofthe I recess or depression, said frame being also provlded with slots or openings, Whlch receive portions of metal of. the body, and 'a lug projecting from the frame for securing the brake shoe to a brake head.

'In testimony that I claim'the foregoing as my own, I have hereto a'llixed my signature in the presenceof two Witnesses.

I HENRY H. URQUHART.
